Definitions

  • This invention relates to a spring unit for a bed, for example a sprung base for a divan bed, or a mattress.
  • a similar spring unit with parallel rows of continuous springs arranged lengthwise of the unit is longitudinally divided into two distinct areas with different load deflection properties to suit the different weights and/or hardness requirements of a pair of users of the double bed spring unit.
  • a spring unit comprising a plurality of longitudinally extending rows each made from a continuous length of wire formed into spaced coils, one or more rows of springs at each longitudinal edge of the unit being made of increased firmness so as to increase the firmness of the spring unit at said edges and inhibit a user from rolling off the unit over said edges.
  • Fig. 1 is a diagrammatic plan view of one embodiment of spring unit in accordance with the invention.
  • Fig. 2 is a side view of one row of springs of Fig. 1;
  • Fig. 3 is a perspective view of part of the spring unit of Fig. l;
  • Fig. 4 is a diagrammatic plan view of another embodiment of spring unit in accordance with the invention.
  • Figs. 5 and 6 are diagrammatic plan views of spring units illustrating the invention.
  • a continuous spring row 1 comprises pairs of coil springs 3, 4 with upwardly convergent axis.
  • the springs of each pair 3, 4 are interconnected by their upper ends at 5 and the adjacent pairs are interconnected by their lower ends at 6.
  • Fig. 4 shows a spring unit of the kind described in the cited UK Patent Application. Lengthwise rows 7 of continuous spring units are interconnected by transverse helicals 8 within a rectangular frame 9.
  • Figs. 1 to 3 and Fig. 4 are well known for example from the cited patent specifications. Hitherto, however, the spring rows have been of identical construction throughout all or a substantial part of the spring unit. By contrast, in the spring unit of the invention a row of springs at each longitudinal edge of the unit is made of increased firmness.
  • Fig. 5 shows a spring unit for a divan base or mattress of a single bed with continuous spring rows 9 extending longitudinally in equally spaced parallel relationship.
  • the spring unit may be of the kind illustrated in Figs. 1 to 3 or Fig. 4.
  • the outermost row 9a at each longitudinal edge of the spring unit is of increased firmness in order to inhibit roll-off of the user.
  • the increased firmness is achieved by increasing the gauge of the wire thereby increasing the resistance to compression of the constituent springs.
  • some other change producing the same result may be effected, e.g. the diameter of the spring coils may be changed.
  • a central row 9b may be made of increased firmness as well as the edge rows 9a. This inhibits rolling together of the users of the spring unit.
  • additional edge or central rows may be made of increased firmness in order to improve the efficacy of the roll prevention features.
  • the remaining spring rows 9 are preferably of uniform firmness but in a modification these rows are made with different load deflection properties in two distinct areas of the spring unit.
  • transverse zones of different firmness as is well known for adapting the spring unit to the different loadings of different parts of the human body.
  • a transverse central section of the spring unit may be of greater firmness than adjacent head and foot sections of the unit. This can be achieved by varying the spacing of the coil springs in the individual rows so that the firmness of the spring unit is increased in the areas in which the spring density is higher and reduced in the areas in which it is lower.

Abstract

Un élément à ressorts comporte des rangées (9) s'étendant longitudinalement, chacune composée d'une longueur de fil métallique continue agencée en une multiplicité de boudins contigus. Les rangées de ressorts (9) sont identiques excepté sur les bords longitudinaux de l'élément à ressorts (9a) où les rangées respectives (9a) sont dotées d'une fermeté accrue afin d'éviter que l'utilisateur ne roule hors de lit. Dans un élément à ressorts double, une ou plusieurs rangées centrales peuvent de même être dotées d'une plus grande fermeté afin d'éviter que les deux utilisateurs ne roulent l'un vers l'autre.
